Technical Field

[0001] This utility model relates to the field of automotive battery pack fixing technology, specifically a quick fixing structure for new energy vehicle battery packs. Background Technology

[0002] Electric vehicle batteries are chemical energy storage devices that provide driving power for electric vehicles. They are divided into two categories: storage batteries and fuel cells. Storage batteries store electrical energy through reversible electrochemical reactions. The entire system consists of multiple battery packs and corresponding management systems, high-voltage circuits, low-voltage circuits, and mechanical assemblies. Types include lead-acid batteries, nickel-metal hydride batteries, and lithium-ion batteries. Among them, lithium-ion batteries dominate the market due to their high energy density and long cycle life. Existing technologies use bolts or complex structures to connect, unlock, and lock the battery pack to the vehicle frame.

[0003] Currently, bolted connections have a short lifespan. If they reach their durability limit quickly, the bolts and accessories need to be replaced. Other complex battery swapping units are costly and also result in longer swapping times. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rapid fixing structure for new energy vehicle battery packs, thereby solving the problems mentioned in the background art, such as the short service life of current bolted connection structures, the need to replace bolts and accessories when they reach their durability limit, the high cost of other complex battery swapping units, and the long battery swapping time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-fixing structure for a new energy vehicle battery pack, comprising a base, a fixing seat fixedly mounted on the outer surface of the base, a torsion member provided on the outer surface of the base, a worm gear rotatably connected to the outer surface of the fixing seat, a worm wheel meshing with the outer surface of the worm gear, a gear plate fixedly mounted on the outer surface of the worm wheel, two rack plates meshing with the outer surface of the gear plate, insert blocks fixedly mounted on the outer surfaces of the two rack plates, a recessed platform formed on the outer surface of the base, a connecting seat inserted into the outer surface of the recessed platform, slots formed on both sides of the connecting seat, the insert blocks being inserted into the slots through the recessed platform, a heat dissipation plate fixedly mounted on the outer surface of the connecting seat, and a battery pack fixedly mounted on the outer surface of the heat dissipation plate.

[0006] Preferably, four protective frames are fixedly installed on the outer surface of the base. The four protective frames are arranged in a rectangular array. Springs and telescopic components are fixedly installed on the outer surface of each of the four protective frames. The telescopic component is located in the middle of the spring component. Limiting frames are fixedly installed on the output ends of the spring component and the telescopic component. The four limiting frames are connected to the corners of the battery pack. The heat sink is attached to the base.

[0007] Preferably, the two rack plates are disposed on both sides of the gear plate, the base adopts a heat dissipation structure, the heat dissipation structure of the base includes a heat dissipation channel opened inside the base, the two ends of the heat dissipation channel are respectively connected to an air inlet pipe and an air outlet pipe, a cooling fan is installed at the outer end of the air inlet pipe, a connector is fixedly installed on the outer surface of the base, and the outer surface of the connector is provided with mounting holes.

[0008] Preferably, the torsion member includes a fixing block fixedly installed on the outer surface of the base, a rotating rod rotatably connected inside the fixing block, a torsion spring fixedly sleeved on the outer surface of the rotating rod, and one end of the rotating rod being fixedly connected to one end of the worm gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This new energy vehicle battery pack quick-fixing structure uses a base as a support foundation. When the torsion component is used as the power input, it drives the worm gear on the fixing seat to rotate. The worm gear meshes with the worm wheel, driving the worm wheel and the gear plate fixed on the outer surface to rotate. The gear plate then synchronously drives the two rack plates meshing with it to move towards each other along the base. This allows the inserts on the rack plates to be guided along the base recess and accurately inserted into the slots on both sides of the connecting seat in the recess, thus connecting the connecting seat and the base. This achieves the effect of durable use and convenient quick battery swapping.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Please refer to Figures 1-5. A quick-fixing structure for a new energy vehicle battery pack includes a base 1, a fixing seat 3 fixedly mounted on the outer surface of the base 1, a torsion member 2 provided on the outer surface of the base 1, a worm gear 4 rotatably connected to the outer surface of the fixing seat 3, a worm wheel 5 meshing with the outer surface of the worm gear 4, a gear plate 6 fixedly mounted on the outer surface of the worm wheel 5, two rack plates 7 meshing with the outer surface of the gear plate 6, and insert blocks 8 fixedly mounted on the outer surfaces of both rack plates 7. A recess is formed on the outer surface of the base 1, and a connecting seat 9 is inserted and connected to the outer surface of the recess. Slots 10 are formed on both sides of the connecting seat 9, and the insert blocks 8 are inserted and connected to the slots 10 through the recess. A heat sink 11 is fixedly mounted on the outer surface of the connecting seat 9, and a battery pack is fixedly mounted on the outer surface of the heat sink 11.

[0017] Specifically, with the base 1 as the supporting foundation, when the torsion component 2, which is the power input, is twisted, it will drive the worm 4 on the fixed seat 3 to rotate. The worm 4, through meshing with the worm wheel 5, drives the worm wheel 5 and the gear plate 6 fixed on the outer surface to rotate. The gear plate 6 then synchronously drives the two rack plates 7 that mesh with it to move towards each other along the base 1, so that the inserts 8 on the rack plates 7 are guided along the concave platform of the base 1 and accurately inserted into the slots 10 on both sides of the connecting seat 9 in the concave platform, thereby realizing the connection between the connecting seat 9 and the base 1, thus achieving the effect of durable use and convenient quick battery replacement.

[0018] In the embodiment: two rack plates 7 are disposed on both sides of the gear disk 6, the base 1 adopts a heat dissipation structure, the heat dissipation structure of the base 1 includes a heat dissipation channel opened inside the base 1, the two ends of the heat dissipation channel are respectively connected to an air inlet pipe and an air outlet pipe, a cooling fan is installed at the outer end of the air inlet pipe, and a connector is fixedly installed on the outer surface of the base 1, and the outer surface of the connector is provided with mounting holes.

[0019] Specifically, the symmetrical layout of the rack plate 7 avoids unilateral offset, improving locking accuracy and reliability; the heat dissipation channel inside the base 1 is connected to the air inlet pipe and the air outlet pipe at both ends. After the cooling fan at the outer end of the air inlet pipe is started, it can draw in cold air from the outside into the channel, absorb the heat of the battery pack conducted by the base 1, surrounding transmission components and connecting seat 9, and then exhaust the hot air through the air outlet pipe, forming a circulating heat dissipation path, preventing the transmission components from getting stuck at high temperature and assisting in strengthening the heat dissipation of the battery pack, thus extending battery life; in addition, the connecting parts fixed on the outer surface of the base 1 can be precisely fixed to the designated position on the car through the mounting holes they have, together with fasteners, without the need for additional drilling, simplifying the assembly process, improving installation efficiency, and the standardized fixing method ensures that the base 1 does not shift during driving, enhancing the overall structural stability.

[0020] In the embodiment: the torsion member 2 includes a fixing block fixedly installed on the outer surface of the base 1, a rotating rod is rotatably connected inside the fixing block, a torsion spring is fixedly sleeved on the outer surface of the rotating rod, and one end of the rotating rod is fixedly connected to one end of the worm gear 4.

[0021] Specifically, when the lever is manually rotated, it rotates stably within the fixed block and drives the worm gear 4 to rotate synchronously. At the same time, the torsion spring deforms and stores energy. When the lever is released, the torsion spring releases its elastic force, which can drive the lever and worm gear 4 to reset in the opposite direction, providing reverse power for unlocking the battery pack.

[0022] Working principle: A fixed seat 3 is fixedly installed on the outer surface of the base 1. A torsion member 2 is provided on the outer surface of the base 1. A worm gear 4 is rotatably connected to the outer surface of the fixed seat 3. At the same time, a worm wheel 5 is meshed with the outer surface of the worm gear 4. A gear plate 6 is fixedly installed on the outer surface of the worm wheel 5. Two rack plates 7 are meshed with the outer surface of the gear plate 6. Insert blocks 8 are fixedly installed on the outer surfaces of the two rack plates 7. A recess is formed on the outer surface of the base 1, and a connecting seat 9 is inserted and connected to the outer surface of the recess. Slots 10 are formed on both sides of the connecting seat 9. The insert blocks 8 are inserted and connected to the slots 10 through the recess. A heat sink 11 is fixedly installed on the outer surface of the connecting seat 9. A battery pack is fixedly mounted on the surface, with the base 1 as the supporting foundation. When the torsion member 2, which is the power input, is twisted, it drives the worm 4 on the fixed seat 3 to rotate. The worm 4 drives the worm wheel 5 and the gear plate 6 fixed on the outer surface to rotate through meshing with the worm wheel 5. The gear plate 6 then synchronously drives the two rack plates 7 that mesh with it to move towards each other along the base 1, so that the inserts 8 on the rack plates 7 are guided along the concave platform of the base 1 and accurately inserted into the slots 10 on both sides of the connecting seat 9 in the concave platform, thereby realizing the connection between the connecting seat 9 and the base 1. Compared with related technologies, the quick fixing structure for a new energy vehicle battery pack provided by this utility model has the following beneficial effects: thus achieving the effects of durable use and convenient quick battery swapping. Example

[0023] Please refer to Figures 1-5. Four guards 12 are fixedly installed on the outer surface of the base 1. The four guards 12 are arranged in a rectangular array. Springs 14 and telescopic members 13 are fixedly installed on the outer surface of each of the four guards 12. The telescopic member 13 is located in the middle of the spring 14. Limiting brackets 15 are fixedly installed at the output ends of the spring 14 and the telescopic member 13. The four limiting brackets 15 are connected to the corners of the battery pack. The heat sink 11 is attached to the base 1.

[0024] Specifically, the four protective frames 12 arranged in a rectangular array outside the base 1 have springs 14 on their outer surfaces and protective pads 16 at the output end corresponding to the corners of the battery pack. When impacted, the protective pads 16 cause the telescopic components 13 to contract and the springs 14 to compress, absorbing energy together. After the impact, the springs 14 cause the telescopic components 13 to reset and continue to provide protection, thereby achieving the comprehensive effects of fast battery pack fixation, efficient heat dissipation, comprehensive protection and stable installation.

[0025] In this embodiment: a protective pad 16 is fixedly attached to the outer surface of the limiting frame 15. The protective pad 16 is made of rubber and has an anti-slip texture on its outer surface.

[0026] Specifically, the rectangular array layout of the four protective frames 12 ensures comprehensive coverage and protection of the four corners of the battery pack, with no blind spots. The rubber buffer pad absorbs impact energy through elastic deformation, and in conjunction with the spring 14 and the telescopic component 13, it further enhances the impact absorption capacity, significantly weakens the impact force transmitted to the corners of the battery pack, and prevents the corners of the battery pack from deforming or being damaged due to impact. The anti-slip texture on the outside of the buffer pad increases the friction with the corners of the battery pack, preventing the two from sliding relative to each other when the vehicle bumps or impacts, ensuring that the protective pad 16 always fits precisely with the corners of the battery pack, and avoiding protection failure. At the same time, the rubber material is soft and wear-resistant, which can reduce the direct friction between the protective pad 16 and the battery pack shell, protect the appearance and structural integrity of the battery pack, and further improve the safety and durability of the battery pack.

[0027] In this embodiment: the connecting seat 9 and the heat sink 11 are fixedly connected by thermally conductive adhesive, and the heat sink 11 is made of aluminum alloy.

[0028] Specifically, the thermally conductive adhesive between the connector 9 and the heat sink 11 eliminates the air insulation layer in the gap between the two, significantly improving the heat transfer efficiency from the connector 9 to the heat sink 11 and preventing heat accumulation in the connector 9. The aluminum alloy heat sink 11, with its high thermal conductivity and good heat dissipation performance, can quickly disperse concentrated heat to the entire surface of the plate, increasing the heat dissipation contact area with the base 1 and further accelerating the heat transfer to the base 1. Combined with the circulating heat dissipation of the heat dissipation channel of the base 1, a multi-layer high-efficiency heat dissipation system is formed, which significantly reduces the operating temperature of the battery pack and effectively avoids problems such as capacity decay and shortened lifespan of the battery due to high temperature. At the same time, it ensures that the base 1 and transmission components operate stably at a suitable temperature and reduces the risk of transmission jamming caused by high temperature.

[0029] Working principle: Four protective frames 12 are fixedly installed on the outer surface of the base 1. The four protective frames 12 are arranged in a rectangular array. Springs 14 and telescopic members 13 are fixedly installed on the outer surface of each of the four protective frames 12. At the same time, the telescopic members 13 are located in the middle of the springs 14. Limiting frames 15 are fixedly installed at the output ends of the springs 14 and the telescopic members 13. The four limiting frames 15 are connected to the corners of the battery pack. The heat dissipation plate 11 is attached to the base 1. The four protective frames 12 arranged in a rectangular array outside the base 1 have springs 14 and protective pads 16 at the output ends corresponding to the corners of the battery pack. When impacted, the protective pads 16 drive the telescopic members 13 to contract and the springs 14 to compress together to absorb energy. After the impact, the springs 14 drive the telescopic members 13 to reset and continue to protect. Compared with related technologies, the new energy vehicle battery pack quick fixing structure provided by this utility model has the following beneficial effects: thus achieving the comprehensive effects of quick fixing of the battery pack, efficient heat dissipation, comprehensive protection and stable installation.
